It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0024] Example 1

[0025] An automatic pressing device for tobacco packing comprises a box body 1, one end of the box body 1 is open, the outer wall of the box body 1 is provided with a driving device 2, the output end of the driving device 2 is connected to a pressing plate 3, the pressing plate 3 extends from the open end of the box body 1 into the box body 1, and the driving device 2 drives the pressing plate 3 to move; the driving device 2 is also provided with a limiting device 4, the driving device 2 is electrically connected to the limiting device 4, the limiting device 4 is combined with the driving device 2, and controls the pressing depth of the pressing plate 3; the bottom of the box body 1 is also provided with a sensing device, the sensing device is electrically connected to the driving device 2, and the sensing device is used to control the opening and closing of the driving device 2. The driving device 2 is provided with two groups, which are respectively arranged at the upper end of the outer wall of the box body 1, and the output end of the driving device 2 is higher than the open end of the box body 1. The two groups of driving devices 2 are arranged oppositely on the box body 1. The driving device 3 is symmetrically arranged on the box body 1. The driving device 2 includes a driving motor 21 and a speed reducer 22. The driving device 2 is key-connected to the speed reducer 22, and the output end of the speed reducer 22 is connected to the pressing plate 3. A connecting rod is provided at the end of the pressing plate 3 close to the open end of the box body 1. The connecting rod is fixedly connected to the pressing plate 3, such as by welding. The connecting rod is used to connect the output end of the driving device 2 and the pressing plate 3, so that the pressing plate 3 can achieve arc motion under the action of the driving device 2. The driving device includes a driving motor 21 and a speed reducer 22. The driving motor 21 is used to drive the pressing plate 3 to move. The speed reducer 22 converts the rotation speed of the driving motor 21 into a suitable speed and torque, and transmits it to the above-mentioned connecting rod, so as to drive the pressing plate 3 to move in an arc.

[0026] Specifically, the pressing plate 3 includes a first pressing plate 31 and a second pressing plate 32, and the first pressing plate 31 and the second pressing plate 32 are arranged at an angle. The first pressing plate 31 exceeds the upper edge of the opening end of the box body 1, and the first pressing plate 31 and the second pressing plate 32 are arranged at an angle, which can press the tobacco leaves in the box body 1 at a certain angle, thereby achieving a better pressing effect.

[0027] Specifically, the angle is an obtuse angle. When the angle is set to an obtuse angle, the pressing plate 3 can move better under the drive of the driving device 3 during use, and can better press the tobacco leaves.

[0028] Specifically, the limit device 4 includes an induction iron 41 and a proximity switch 42, wherein the proximity switch 42 includes an upper limit proximity switch 421 and a lower limit proximity switch 422, and the induction iron 41 moves between the upper limit proximity switch 421 and the lower limit proximity switch 422. The induction iron 41 is connected to the other end of the output shaft of the reducer 22, that is, the induction iron 41 and the pressing plate 3 are respectively connected to both sides of the reducer 22, and the induction iron 41 has the same movement trajectory as the pressing plate 3. The induction iron 41 cooperates with the proximity switch 42 to transmit an electrical signal to the drive device 2 to control the movement trajectory of the pressing plate 3.

[0029] Specifically, it also includes a control system, which is electrically connected to the driving device 2, the limiting device 4, and the sensing device. The control system can be a PLC controller.

[0030] When the present application is in use, it works in conjunction with a tobacco conveying mechanism. Before use, the threshold value of the sensing device is preset. Specifically, after the conveyor belt located above the box body 1 conveys the material into the box body 1, when it reaches the preset value of the sensing device, the sensing device can be set as a pressure sensor. The induction device receives the signal and converts it into an electrical signal. After receiving the above electrical signal, the controller starts the drive motor 21. The drive motor 21 starts working in cooperation with the reducer 22, driving the pressing plate 3 and the induction iron 41 to move downward. The pressing plate 3 makes an arc movement in the box body 1 to loosen and press the tobacco leaves. When it moves downward until the induction iron approaches the lower limit proximity switch 422, the lower limit proximity switch 422 sends a signal to the controller. The controller receives the signal and controls the drive motor 21 to reverse, driving the induction iron 41 and the pressing plate 3 to move upward. When the induction iron 41 approaches the upper limit proximity switch 421, the principle is the same as above. In this process, the pressing plate 3 repeatedly presses the tobacco leaves in the box body 1 loosely, so that the gap between the tobacco leaves is reduced during packing, and the tobacco leaves are packed more tightly. The whole process has a simple structure, convenient operation, low cost and convenient maintenance.

[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
